EMANUEL W. SWEIG-ARD, OF CHICAGO, ILLINOIS.

PHOTOGRAPHIC COPY-HOLDER.

Application filed March 16, 1914.

To all whom it may concern:

Be it known that I, EMANUEL TV. SWEIG- nun, a. citizen of the UnitedStates, and a resident of the city of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inPhotographic Copy-Holders, of which the following is a specification.

This invention relates to improvements in a holder to be used forholding pictures of various kinds and of different sizes, in properposition and condition in front of a camera, for the purpose ofreproducing the same thereby, and it consists in certain peculiaritiesof the construction, novel arrangement and operation of the variousparts thereof, as will be hereinafter more fully set forth andspecifically claimed.

The principal object of the invention is to furnish a photographic copyholder, which shall be simple and inexpensive in construction, strongand durable, proof against warping and otherwise more efficient inoperation than such holders heretofore in general use.

Another object is to provide a copy-holder of the above named generalcharacter, which shall be so made that, if desired, it may be placed andpermanently maintained in an upright position in a-linement with thefront of the camera. and the field of the lens, in which position, thecopy can be placed and secured thereon without the use of glue, paste,tacks and the like, or can be quickly removed therefrom, thus dispensingwith the necessity of handling and changing the position of the holderevery time a different copy is placed thereon, as in the old way, andbesides, avoids marring or soiling the board with tackholes and paste.

A further object is to provide the holder with means for clamping andholding the copy against the face of the holder in such a manner as toprevent buckling, and which, when adjusted will automatically place andhold the copy in the center of the holder. 1

Other objects and advantages of the in vention will be disclosed in thesubjoined description and explanation.

In the accompanying drawings, which serve to illustrate an embodiment ofthe inventionFigure 1 is a face view of a photographic copy holderconstructed according to one form of the invention and illustratingparts thereof broken away or removed Specification of Letters Patent.

Like numerals of reference refer to corresponding parts throughout thedifferent views of the drawings.

Referring now to Figs. 1, 2 and 5 of the drawings, the reference numeral12 designates as a whole a rectangular frame, which may be made of anysuitable size and material, and bordered externally with a channeledcasing 13, which casing is preferably made of wood and securedto theouter surface of the frame 12, by means of screws or otherwise. Locatedbetween two of the parallel sides, say the top and bottom of the frame12, is a copy-holdin g board 1 1, which is preferably made of good hardwood and of a single piece, with its front face perfectly smooth andflat. This board overlaps two of the parallel sides of the frame 12,which, in the present instance, are shown as the vertical sides thereof.The frame 12 is provided on its inner perimeter with a groove 15, intowhich grooves are extended the free ends of metal clips or brackets 16,a series of which are secured to the rear surface of the board 14, nearits edges. At each of its inner corners the frame 12 has secured theretoan angle bracket 17, from two of which are extended diagonally acrossthe frame rods 18, which are connected by means of turn-buckles 19 toeye-rods 20, one of which is secured to each of the brackets 17 at thecorners of the frame 12, opposite the corners to which the rods 18 areconnected. At about midway between its side edges at its top and bottomthe board 14 is rigidly connected to the upper and lower portions of theframe 12 by means of angle brackets 21., which will hold the frame 12and board 14 together at said points, but it will be understood that asthe clips or brackets 16 loosely engage the frame 12 compensation forshrinkage or expansion, due to the action of the atmosphere on the board14 will be afforded, thus preventing the board warping.

Journaled in suitable bearings 22 at one side of the frame 12, near itsupper and lower ends, is an operating rod 23, which may be provided witha knob or handle 24, at one of its ends, used for turning the same. Neareach of its ends the operating rod 23 has mounted thereon a smallsprocket wheel 25, which is inclosed by the 'channeled casing 13 at eachend of the frame. Secured'to the opposite side of the frame 12, neareach of its ends is a bearing member 26, each of which is provided witha transverse opening 27 for the reception of a rod or shaft 28, whichhas mounted'thereon at each of'its ends a grooved pulley 29.

As is clearly shown in Fig. 4, each of the members 26 is fastened nearone of its ends to the frame 12 and is provided at its other end with ascrew 30, which is extended through a suitable opening in the casing 13,and rests at its inner end against a plate 31 on the side of the frame.J ournaled at the top and bottom, or each end of'the frame 12, aboutmidway between its sides, are a pair of double grooved pulleys 32, overwhich is passed an endless chain 33, which also extends around thesprocket wheels 25 and 29, at the ends of the'shafts 23 and 28, at thetop and bottom of the frame. By journaling the shaft 28 in the bearings26, it is 'a-pparent that said bearings may be adjusted by turning thescrews 30 in the properdirection to force the bearing outwardly orinwardly, as desired, thus affording means for taking up or increasingthe slack in the chains 33, which are used for propelling'the clampingbars 34, which bars are extended in parallelism across the board 14 fromits top to its bottom. Each of these bars is provided on its innersurface with a series of inwardly extended projections 35, which havetheir free ends upturned as at 36 to rest against the edge of the copy37 on which the picture to be reproduced is displayed. At each of itsends, each of the bars 34 is provided with a bracket 38, which has apair of outwardly extended prongs 39 to engage the links of the chain 33so that when said chain is moved around the pulleys 32 and sprocketwheels 25 and 29 the bars 34 will be advanced toward one another orseparated, as may be desired. Each of the brackets 38 is provided on itssurface opposite the prongs 39 with an extension 40, which fits into agroove 41 formed in each of the end pieces of the frame at the top andbottom thereof. Hinged to each of the bars 34 on the inner surfacethereof is a holding-strip 42 for the copy 37, each of whichholding-strips may be provided with felt 43 to rest against the copy andprevent marring the same.

As is clearly shown in Figs. 1 and 2 the strips 42 are connected to thebars 34 by means'of torsion springs 44 which are used to hold the strips42 in position against the copv 37, or, if desired, to hold them awayfrom the picture or'board as shown in the sectional part of Fig. 2 ofthe drawings. Pivotally'secured at one'of its ends to each of the bars34 so as to be adapted to swing in a plane'with the board 14 are one ormore spring arms 45, which are bent over the strips 42am have their freeends projected to near the face of the board 14. Each of the arms 45 isprovided at its free end with an adjustable arm 46 to rest on the copy37 so as to prevent the same buckling when a large copy is used. Thearms 46 are adjustably connected to the arms 45 by swivels 47, or in anyother suitable manner.

In Figs. 6 and 7 is shown a modification in the'construction of theholding-strips for the copy, which consists in employing a strip 42",which extends from each of the brackets 38 and is journaled in the upperportions of said brackets, the latter being provided with suitableopenings 48 for said journals. In this modification each of the strips42 is connected at one of its ends to the bracket 38 by means of aspring 49, which will act to hold the strip 42 against the copy 37 asshown by full lines in Fig. 6, butwhen it is desired to raise the strip42 out of the way of the copy 37, it can be done by means of a crankhandle 50 connected to one end of said strip, when the parts will assumeabout the position shown by dotted lines in Fig. 6 of the drawings.

By reference to Figs. 1 and 2 of the drawings, it will be seen that theendless chain 33 passes over one of the pulleys 32, and. under the otherpulley 32, and thence around the sprocket 29, and from thence over thepulley 32 adjacent to said sprocket, and then under the other pulley 32,and from thence around the sprocket 25 on the operating shaft. Thisarrangement is carried out at each end, or the top and bottom of theframe, and it will be understood that by turning the operating rod 23 inthe proper direction, the clamping bars 3 1 will be caused to approacheach other so as to press the upturned portions 36 of the projections 35against the copy, and thus hold it in the proper position on the board,when the holding strips can be turned down so as to firmly secure thecopy in place. By turning the operating rod 23 in the oppositedirection, it is obvious that the clamping bars 34 will be separated ormoved from each other, so as to permit of the insertion therebetween ofa copy sheet of a larger size, if desired.

In Fig. 9 of the drawings, is shown a modification in the means foradvancing and retracting the clamping bars, which consists in employingat opposite sides of the board 14 a pair of screw shafts 51 and 52,which are journaled on suitable brackets 53 secured to the board. Theinner end of each pair of the shafts 51 and 52 have mounted thereonbeveled gears 54:, which mesh withbeveled gears 55 mounted on anoperating shaft 56 near each of its ends, which shaft is provided with ahandle 57 for turning the same, and is also journaled in suitablebrackets 53 secured to the board. Mounted on each of the screw shafts 52is a screw threaded collar 58 which are connected together by means of arod or bar 59, which extends across the face of the board 14, from itstop to its bottom, as shown. Each of the screw shafts 51 has mountedthereon a screw threaded collar 60, which are connected together bymeans of a rod 59 extended across the face of the board 141 inparallelism with the rod 59 first above mentioned. Each of the rods 59may be equipped with a clamping bar 3 1 and holding strip 42 of theconstruction shown in Figs. 1 and 2 and above described, or each of themmay be equipped with clamping bars and holding strips of theconstruction shown in Figs. 6 and 7 of the drawings.

In Fig. 10 is shown another modification in the means for advancing andretracting the clamping-bars, which consists in the employment of ashaft 61, journaled at the opposite edges of the board 1 1, and eachhaving. right and left screw threads thereon. Each of the shafts 61 isprovided at one of its ends with a beveled gear 62, which gears meshwith beveled gears 63 mounted on an operating shaft 64: near each of itsends, which latter shaft is vertically journaled on brackets 53 at oneside of the board and may be provided with a handle 57 for turning thesame. The shafts 61 are each provided with collars 65 one of whichengages the right screw threads and the other the left screw threads, oneach of said shafts. These collars are connected together by means ofrods 66 extended in parallelism across the face of the board 14 and saidrods may be equipped with clamping bars and holding strips of anydesired construction.

By using the diagonal rods 18 and turnbuckles 19 it is evident thatshould the frame warp or get out of alinement, this defect can becorrected by tightening one or the other of the turn buckles.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. In a photographic copy holder, the combination with a holding-board,of a pair of clamping-bars for the copy extended in parallelism acrossthe face of said board,'a spring actuated holding strip secured to eachof said bars and extended longitudinally therewith, and means mounted onthe board and connected to said bars for simultaneously moving themtoward and from each other.
